Daily Protein Calculator
Enter weight and your own g/kg. 70 kg × 1.6 gives 112 g/day. 80 × 1.2 gives 96. 60 × 2 gives 120. No goal list here. That list lives on protein requirement.

Enter data and click Calculate.
Not a clinic verdict and not a prescription. The calculator multiplies weight by g/kg. Kidney or liver disease: a doctor first.
How it works
Daily protein in this calculator is weight in kg times a g/kg factor. 70 × 1.6 = 112. The result is 112 g/day. 80 × 1.2 = 96 g/day. 60 × 2 = 120 g/day. Height and age do not enter this product.
You enter the factor yourself. There is no maintain / cut / muscle button. Those 1.0, 2.0, and 1.8 rates live on the protein page. 70 kg and 1.6 give 112 whatever the label goal says.
With a US header, weight is in pounds and the calculator converts to kg before it multiplies. The US factor is g/lb and returns to g/kg. The 112, 96, and 120 examples are from a metric header.
Optional height, age, sex, and activity estimate BMR and TDEE and the share of kcal from protein. 112 g × 4 = 448 kcal. Without those fields you still get 112 g/day.
Enter weight, enter g/kg, then Calculate. A comma in 1.6 parses. 200 g at 60 kg is about 3.3 g/kg, outside common sport rates. Not a clinic diet.
70 kg × 1.6 gives 112 g/day. 80 × 1.2 gives 96 g/day. 60 × 2 gives 120 g/day. Daily TDEE is on the neighbouring page, not inside this product. Protein is in grams, not calories.
g = weight[kg] × g/kg
Daily protein = weight × g/kg. 70 × 1.6 gives 112 g/day. Height does not enter this product.

Common questions
How much daily protein at 70 kg and 1.6 g/kg?
112 g/day. 70 × 1.6 = 112. The calculator appends g/day.
What about 80 kg and 1.2?
96 g/day. 80 × 1.2 = 96.
What about 60 kg and 2?
120 g/day. 60 × 2 = 120.
Do I have to enter height and age?
Not for 112 g/day. Those fields estimate BMR and TDEE, not the product itself.
Where are maintain and cut goals?
On the protein page. Here you enter your own g/kg.
Is 112 g a prescription?
No. A estimate from a product. Kidney disease: a doctor first, not this rate.
Does a US header change 70 × 1.6?
Yes. Then 70 is pounds and 1.6 is g/lb. The 112 examples are metric.
How many kcal in 112 g?
448. The calculator multiplies grams by 4 when it shows the kcal row.
Does a comma in 1.6 work?
Yes. 1.6 and 1,6 both give 112 g/day.
How do I calculate daily protein from g/kg?
Result = weight (kg) × chosen g/kg. At 70 kg and 1.6: 112 g/day. At 80 kg and 1.2: 96. At 60 kg and 2: 120. Height is not in this product.
How is this different from the protein requirement calculator?
That page picks a goal from a list (maintenance, cut, and so on) with ready rates. Here you enter your own g/kg. Both results are daily grams from body mass.
Is this a full macro calculator (P/C/F)?
No. It only computes protein from weight and g/kg. Carbohydrate and fat from an energy percent live on separate pages.
Is 112 g medical advice?
No. It is an estimate from the product. With kidney disease or a clinical diet, see a clinician first — not this calculator.
